Description

Technical Field

[0001] This utility model relates to the field of mechanical flange technology, and in particular to a mechanical flange connecting plate with a stable structure. Background Technology

[0002] Mechanical flanges, as key interface components connecting shafts and drive shafts, are essential for achieving synchronous rotation and energy transfer between the two shafts. They play a vital role in industrial production.

[0003] However, most mechanical flange connecting plates currently in use are welded to the connecting shaft. Although this can ensure the stability of the connection, cracks often appear after welding over time, leading to a decrease in structural stability. In addition, during welding, the flange and connecting shaft need to be adjusted to be coaxial multiple times using tools to ensure transmission stability, which reduces welding efficiency. Therefore, this application proposes a mechanical flange connecting plate with a stable structure. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a mechanical flange connection plate with a stable structure.

[0005] An embodiment of this utility model provides a mechanical flange connection disc with a stable structure, comprising:

[0006] Flange and connecting shaft;

[0007] A connecting structure includes a rectangular block fixed coaxially with a connecting shaft. The connecting shaft has a rectangular groove coaxially arranged. When the rectangular block is located in the rectangular groove, the flange is coaxial with the connecting shaft. The flange and the connecting shaft are connected by welding. Positioning shafts distributed along the diameter direction of the connecting shaft are provided through the connecting shaft and the rectangular block.

[0008] Furthermore, the rectangular block and the flange are integrally formed by casting.

[0009] Furthermore, a first through hole is provided through the connecting shaft, a second through hole is fixed on the rectangular block, and the positioning shaft passes through the first through hole and the second through hole and is interference-fitted.

[0010] Furthermore, both the rectangular block and the rectangular groove are rectangular, and when the rectangular block is slidably connected in the rectangular groove, the first through hole and the second through hole can be opposite each other.

[0011] Furthermore, the length of the positioning shaft is less than the diameter of the connecting shaft.

[0012] Furthermore, after the flange is welded to the connecting shaft, a weld seam is formed between the flange and the connecting shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention improves the stability and reliability of the connection by optimizing the connection structure. The matching design of the rectangular block and rectangular groove, as well as the reinforcement effect of the positioning shaft, effectively solves the problems of easy cracking after welding of existing mechanical flange connection plates, and the complex and inefficient coaxial adjustment.

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] This embodiment provides a mechanical flange connection disc with a stable structure, the structure of which is as follows: Figure 1-Figure 3 As shown, it includes flange 1, connecting shaft 2, and connecting structure.

[0022] Flange 1: As the main part of the connecting plate, it is used to connect with other mechanical components.

[0023] Connecting shaft 2: Coaxially arranged with flange 1, used to connect flange 1 to other components. The connecting shaft 2 is provided with a coaxially arranged rectangular groove 8, which is used to accommodate rectangular block 6 to achieve coaxial connection between flange 1 and connecting shaft 2.

[0024] Connection structure: Includes rectangular block 6 and positioning shaft 5. Rectangular block 6 is coaxially fixed with connecting shaft 2 and located within rectangular groove 8, which increases the axial torque of connecting shaft 2 and flange 1, thus making the weld joint less prone to cracking. Positioning shaft 5 passes through connecting shaft 2 and rectangular block 6, and is distributed along the diameter direction of connecting shaft 2 to enhance the stability of the connection.

[0025] During the welding process, due to the coaxial fixation of rectangular block 6 and flange 1, when rectangular block 6 is located within rectangular groove 8, flange 1 and connecting shaft 2 can easily achieve coaxial connection without multiple adjustments, greatly improving welding efficiency. Simultaneously, the matching design of rectangular groove 8 and rectangular block 6, along with the reinforcing effect of positioning shaft 5, effectively improves the stability and reliability of the connection.

[0026] Example 2

[0027] Based on Example 1, this example further proposes another connection method between the rectangular block 6 and the flange 1. Specifically, the rectangular block 6 and the flange 1 are integrally formed by casting. This connection method not only simplifies the manufacturing process but also further enhances the connection strength between the rectangular block 6 and the flange 1, improving the overall stability and reliability.

[0028] Example 3

[0029] Based on Example 1, this example describes in detail the installation method of the positioning shaft 5. For example... Figure 2 As shown, a first through hole 4 is provided through the connecting shaft 2, and a second through hole 7 is fixed on the rectangular block 6. The positioning shaft 5 passes through the first through hole 4 and the second through hole 7 and is fixed together by an interference fit. This installation method is not only simple and convenient, but also effectively prevents the positioning shaft 5 from loosening or falling off during long-term use, further improving the stability and reliability of the connection, and also increasing the axial connection strength between the connecting shaft 2 and the flange 1.

[0030] Meanwhile, both rectangular block 6 and rectangular groove 8 are rectangular in design, allowing rectangular block 6 to slide within rectangular groove 8. When rectangular block 6 slides to the appropriate position (connecting shaft 2 abuts against flange 1), the first through hole 4 and the second through hole 7 align, facilitating the passage and fixation of positioning shaft 5. This design not only simplifies the coaxial adjustment process but also improves the flexibility and convenience of installation.

[0031] Furthermore, the rectangle is set instead of a square so that when the rectangular block 6 is installed in the rectangular slot 8, the first through hole 4 and the second through hole 7 can be aligned.

[0032] Example 4

[0033] Based on Example 1, this example describes the structural features of the flange 1 after welding with the connecting shaft 2. For example... Figure 1 As shown, a weld 3 is formed between flange 1 and connecting shaft 2 after welding. To ensure the quality and strength of weld 3, welding parameters and process conditions should be strictly controlled during the welding process to ensure the uniformity and density of weld 3. At the same time, the presence of weld 3 further enhances the connection strength between flange 1 and connecting shaft 2, improving the overall stability and reliability.

[0034] In summary:

[0035] This invention improves the stability and reliability of the connection by optimizing the connection structure. The matching design of the rectangular block 6 and the rectangular groove 8, as well as the reinforcement effect of the positioning shaft 5, effectively solves the problems of easy cracking after welding of existing mechanical flange connection plates, and the complex and inefficient coaxial adjustment.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
